You mean the D-Wave computer? It seems to be a common misconception that it's a quantum computer in the sense of using coherent superpositions to perform computations - it is not. It's another kind of quantum computer - it performs quantum annealing, which is a way to use quantum effects to accelerate certain cases of simulated annealing. Whether or not the D-Wave computer can actually do anything faster than more traditional methods is up for discussion, but the only one who ever claimed it was a quantum computer in the sense discussed here has been clueless journalists.

The user context doesn't really matter when it runs in kernel space as nothing can stop you from just replacing the user context. Why http parsing is done in kernel space is exactly to maximize performance. As mentioned in TFS you can disable it if you want to. One could argue that it shouldn't be on by default because it doesn't give you much if you are serving dynamic content.

> IIS kernel caching For performance reasons probably. It's optional though. I have no idea about real numbers, but there is always some overhead associated with contex switches which may be reduced if the http stream is assembled in chunks in kernelspace and control is only switched to userspace when a chunk is ready. Also it may be possible to parse the http stream directly from the buffer that the hardware writes the received data to without the overhead of copying the packets to userspace.

While they can write anything in the site's TOS, it may not be legally enforceable depending on where you live. For example I'm not in anyway confirming that I have read the terms when I'm posting this comment, which means it is probably not legally binding in EU. Even if I had to confirm that I agree with the ther terms they may not be legally enforceable as EU has some quite strict laws about unfair contracts.

I don't think you know what "monolithic" means. No one said anything about everything being in the same binary. systemd consists of several components that has been designed to only work with each other. There is no modularity in the sense that there is no modules you can replace or decide whether or not to use.

Flickering and architectural problems. The first is purely cosmetic, but is impossible to fix without making chances to the core protocol. The second means that an order of magnitude more work is required to add new functionality than what could be done with a more modern design.

obviously by ssh admin he means whoever administrates access to ssh, and would allow X forwarding in the sshd_conf file...

You are incorrect. X forwarding still requires giving your local host permission to the x server.

I don't know which distro you use, but usually that is enabled unless whoever administrates access to ssh disables it.

Comment Re:remote desktop vs windows (Score 1) 197

Well, assuming that the ssh admin has permitted ssh forwarding. And that you invoked your ssh client with the appropriate flags. And that you export the DISPLAY variable on the remote host. And that you set your xhost permissions on your own host.

Other than that, nothing to be done.

You mean

ssh -X user@host xterm?

Damn hard that is!
